Reports Download not working

When I am trying to download pdf, cvs or any type from reports I am getting following message: There was a problem processing your request, please contact your administrator and have them verify the logs.

Resolution:

Changed the "Maximum Rows for Reports" value in the iDash Admin Tool GUI to 10000 from 100,000. iDash Server -> General -> Server. The comma (,) in the value was the problem.
